tegra: Migrate to new interfaces
...
- Migrate to bl31_early_platform_setup2().
- Remove references to removed build options.
- Replace zeromem16() by zeromem().
- Use private definition of bl31_params_t.
This is an incomplete migration, the platform doesn't currently compile.

Tegra: Fix up INFO() message
...
With commit cf24229e6ef4 ("Run compiler on debug macros for type
checking"), the compiler will now always evaluate INFO() macro
calls, no matter the LOG_LEVEL value. Therefore, any variable
referenced in the macro has to be be defined.
Address this issue by removing the local variable and using the
expression it was assigned directly in the INFO() call.

Clean usage of void pointers to access symbols
...
Void pointers have been used to access linker symbols, by declaring an
extern pointer, then taking the address of it. This limits symbols
values to aligned pointer values. To remove this restriction an
IMPORT_SYM macro has been introduced, which declares it as a char
pointer and casts it to the required type.

tegra: Fix build errors
...
The 'impl' variable is guarded by the symbol DEBUG, but used in an INFO
level print statement. INFO is defined based on LOG_LEVEL. Hence, builds
would fail when
- DEBUG=0 && LOG_LEVEL>=LOG_LEVEL_INFO with a variable used but not defined
- DEBUG=1 && LOG_LEVEL<LOG_LEVEL_INFO with a variable defined but not used
Fixing this by guarding impl with the same condition that guards INFO.
Fixes ARM-software/tf-issues#490

Tegra: memctrl_v1: disable AHB redirection after cold boot
...
During boot, USB3 and flash media (SDMMC/SATA) devices need access to
IRAM. Because these clients connect to the MC and do not have a direct
path to the IRAM, the MC implements AHB redirection during boot to allow
path to IRAM. In this mode, accesses to a programmed memory address aperture
are directed to the AHB bus, allowing access to the IRAM. The AHB aperture
is defined by the IRAM_BASE_LO and IRAM_BASE_HI registers, which are
initialized to disable this aperture. Once bootup is complete, we must
program IRAM base/top, thus disabling access to IRAM.
This patch provides functionality to disable this access. The tegra port
calls this new function before jumping to the non-secure world during
cold boot.

Tegra: GIC: enable FIQ interrupt handling

Tegra chips support multiple FIQ interrupt sources. These interrupts
are enabled in the GICD/GICC interfaces by the tegra_gic driver. A
new FIQ handler would be added in a subsequent change which can be
registered by the platform code.
This patch adds the GIC programming as part of the tegra_gic_setup()
which now takes an array of all the FIQ interrupts to be enabled for
the platform. The Tegra132 and Tegra210 platforms right now do not
register for any FIQ interrupts themselves, but will definitely use
this support in the future.

This patch maps the TZDRAM carveout used by the BL31. In the near
future BL31 would be running from the TZRAM for security and

the TZRAM loses its state in System Suspend. So, we map the TZDRAM
carveout that the BL31 would use to save its state before entering
System Suspend.
